Abstract

200,577. Wilderman, M. April 12, 1922. Filtering-media.-Porous bodies are made from powder, shavings &c. of partly vulcanized ebonite or of completely vulcanized ebonite covered with a thin layer of unvulcanized or partially vulcanized' ebonite, by bringing the powder &c. into a volume larger than it would occupy under pressure and vulcanizing. According to a modification, the ebonite powder &c. is mixed with a substance such as salt which does not combine with the ebonite, and which can be removed by solution or other means after vulcanizing. Diaphragms &c. capable of resisting alkalies, acids and chlorine may be made from the composition described in Specification 18269/08, [Class 70, India-rubber &c.]. The ebonite may be combined with metal &c. during manufacture, or plates &c. may be made with strengthening ribs, strips &c. of non-porous ebonite. The porosity may be modified by filling the capillaries more or less with substances such as barium sulphate, cement, colloids, or the plates may be employed as supports for other filtering media.
